Not sure if you're still waiting on this, but here's a draft of a PRM 
hwmod for OMAP34xx for testing purposes.  It needs a little more review 
and thought before being ready for merging, but I think it will work for 
your purposes.  The OMAP2430 version should be quite similar.  Comments 
welcome,
